Dogs with ear infections shake their heads, scratch, and show redness, odor, or discharge — diet changes help only when allergies are the cause.
For the full breakdown, see our best Dog Food For Ear Infections guide.
A dog that suddenly shakes its head and paws at its ear isn’t being dramatic. Working out how to identify ear infection symptoms in dogs and what to feed them while they heal comes down to two separate questions, and only one of them involves food. The symptoms tell you when the vet needs to be involved; the feeding part matters only when allergies are driving the problem.
What Are The First Signs Of An Ear Infection In A Dog?
The classic signs are hard to miss: head shaking, scratching or rubbing at the ear and face, redness, swelling, heat, a bad smell, and visible discharge. Discharge ranges from dark brown wax to slimy, pus-like, or crusty material. The ear is often painful — dogs may yelp when it’s touched, flinch when you reach for the head, or hesitate to chew because opening the mouth pulls on the ear.
Either one or both ears can be affected, and the Merck Veterinary Manual notes the signs can appear suddenly or build over time.
